W.N.S. Reaper is a nuclear submarine deployed by the World Navy. It featured briefly in Atlantic Inferno, when it was testing some gyropedoes by firing them at a submarine.

Gyropedoes[]
She's a Maverick![]
One of the gyropedoes went haywire by flying out of the water and going on a collision course with the seabed, causing a fire to spread. International Rescue arrived on-scene and Gordon in Thunderbird 4 put a sealing device on the seabed spot in an attempt to stop the fire from spreading.

Trivia[]
- The model for W.N.S. Reaper was reused as the Clam Class submarine in the episode White As Snow in Captain Scarlet and The Mysterons, the Andersons' next series.
- The Complete Book of Thunderbirds erroneously refers to the sub as the "Reefer".
- The name Reaper appears to be a reference to the USS Thresher, a nuclear-powered attack submarine that sank during diving tests in 1963.
